A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...

An international team of astronomers reports the discovery of a new hyperluminous quasar. The newfound quasar, which received the designation eFEDSJ0828–0139, has a high star-formation rate and its ...

Astronomers from Seoul National University, South Korea and elsewhere report the detection of 62 new luminous quasars as part of the All-sky BRIght, Complete Quasar Survey (AllBRICQS). The discovery ...

This image, taken by NASA’s James Webb Space Telescope, shows an ancient quasar (circled in red) with fewer than expected neighboring galaxies (bright blobs), challenging physicists’ understanding of ...

Astronomers have identified a remarkable population of distant quasars whose radio jets balloon to scales that make our own galaxy look compact, stretching to widths roughly 50 times larger than the ...

Thanks to the Giant Meterwave Radio Telescope (GMRT) in India, a team of astronomers has recently identified 53 new specimens of a rare category of quasars, named giant radio quasars. These objects ...

An artist's depiction shows how a quasar, which is the extremely bright core of a galaxy, unleashes torrents of energy from its central black hole. Credit: NASA / ESA / J. Olmsted (STScI) Scientists ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that. Ultra-self-interacting dark matter clumped into ...
